Are prediction markets legal in Wisconsin?

Contested. Wisconsin’s Attorney General sued Kalshi, Robinhood, Coinbase, Polymarket and Crypto.com in April 2026, alleging illegal sports betting; the companies moved the cases to federal court, where they await rulings. A federal judge refused the CFTC’s request to stop Wisconsin, and that appeal is pending. Sports betting is legal only through tribal casinos.

Of the 56 platforms we review, 12 are open in Wisconsin, 5 with restrictions and 26 not at all; for 13 the terms do not say. Sports betting in Wisconsin: legal only through tribal casinos, under tribal-state compact amendments (doa.wi.gov).

Not legal advice. Eligibility usually follows where you are when you trade, and a platform can refuse an individual account. Checked 4 October 2026.
